XS650: Vibratirry Bowels   Leave a comment

Was cruising through fleabay and found this: …


Pro-1 Racing is now offering ISOTROPIC FINISH services on YAMAHA XS 650 Motorcycle Transmission . Note this is a machine shop service on your transmission. Isotropic Finishing is not a polish process but a super finishing procedure. This process is a two stage chemical process to produce a super finish know as an Isotropic Finish. The first step is a chemical interaction with the metal where a film that is 1 micron thick or 1/100000in. The parts interact with the ceramic media and a vibratirry bowel. The second step is also a chemical reaction that produces the super finish know as the Isotropic Super Finish. This two step process takes about 4-6 hours in each step with a total time of 10-12 hours. Parts are constantly inspected and measured, during both processes. After parts are finished, all parts are Ultra-Sound cleaned and coated with a rust prohibitor.

Parts received are inventoried and digital picture are documented
We would like to have the transmission disassembled if possible,we offer services to remove gears from shafts for an extra charge.
We inspect parts parts and advise if we see issues

We use BV products from Melbourne Australia. I acquired all of the knowledge and procedures during my stay there in 04/ 2015.
The experience was very exciting and I’m looking forward to share all of the beneficial results.


• reduces friction,vibration and noise
• improves Shifting on Vintage bikes and Harley Davidson’s
• Race bike application
• longer life on parts
• reduces lubricant temperatures
• reduces metal to metal pitting
• less inertia= lee friction=reduces fuel consumption
• stress relieves parts

Applications include

• gears and shafts
• camshafts
• crankshafts
• rocker arms
• valve springs
• transmission gears

For more information, please feel free to call;

sorry Charlie, your block’s shortness could have something to do with your vibratirry bowel

In essence this is a vibration finishing process. Uses non-abrasive media. On chemically coated machined parts. Creates a non-directional finish. Removes stress risers. Improves surface finish and edges.

Main benefits seem to be stress relief, reduced friction, less heat.

Isotropic Finish is related to the non-directional vibration finish. The chemical treatment serves to speed this process up

BV Products actually do exist. Couldnt find any medical warnings on their site.
